In summary, the conversation discusses the calculation of the rms voltage generated by a rotating rectangular coil in a uniform magnetic field. The correct answer is achieved by converting the given rpm value to radians per second and using SI units in the formula. ...
magnetic field coilmagnetic field calculationThe formulae for calculating the magnetic field produced by the finite size helical coil with rectangular cross section [J. Todoroki: Kakuyugo Kenkyu 57 (1987) 318] are extended to the case with an arbitrary polygonal cross section. The formulae for ...
The magnetic induction (B) is related to the field intensity (H) as (4.13)B=μH where μ is characteristic of a medium and is known as magnetic permeability. The relative permeability is defined by the ratio of magnetic permeability to that of free space (Dekker, 1959). (4.14)μr=μ/...
In this paper, we present a novel low-frequency sensing solution based on the manipulation of the near-field distribution by employing a passive holographic magnetic metasurface, excited by an active RF coil placed in its reactive region. In particular, the sensing capability is based on the inte...
First, we only consider test cases where the magnetic field is given by a mathematical formula (a magnetic mirror and a Solev'ev equilibrium), in contrast to a real reactor where the field is given by a numerical solution to the Grad-Shafranov equation fitted to experimental data. Second, ...

The measurement conditions are as follows: measurement mode: full loop, maximum magnetic field: 15 kOe, magnetic field step: 40 bit, Time constant of Locking amp: 0.3 sec, Waiting time: 1 sec, and MH average number: 20. After the M-H loop of the measurement sample (the entire magnetic...
In an electrical machine, the magnetic losses or core losses are due to the soft magnetic material operating in a time-varying magnetic field. Core losses are made up of eddy current losses that arise from circulating electrical currents induced in conducting materials (the electrical steel used ...
Using numerical methods to simulate the dynamics would require the use of a time-step size congruent with the particular timescale of the system, set by for example, the dominant Zeeman interaction for systems placed in a strong magnetic field. The Zeeman interaction of electron-nuclear system ...
